Thanks for posting your question today. I'm more than happy to assist you. Typically, we do not offer coding support for third party software. However, depending on what you're trying to accomplish we can attempt to help you find a viable solution.

A 406 error is due to mod security. In instances like this we recommend turning off mod security. Mod security can be turned off for your entire account or for a single domain.

The issue is not with the server itself or the coding, but how your vBulletin software interacts with server. With this being the case, it's the coding within the PHP files causing the issue. The code is not broken but simply using specific coding that is causing mod_security to flag it.

If you would like to turn mod security off for your domain, please feel free to email the request to support@inmotionhosting.com. Also, make sure to include your domain name and the last four of the credit card on file OR the current AMP password for security purposes.
